throttle body pulley swap

[frankenfresh]

are the ca18 and s13 sr20det throttle body pulleys the same? maybe the sr s13 and s14?

I'm thinking about trying out one of these cheepo "Hi-Throttle pulleys"

just wanna see if they make any difference. anyways, they only list them for the ca18 and the s14 sr20. can I use one of these? I will be running an isis intake manifold if it matters.

still wondering here.... anyone?

i run an agency power one for the ka, i did notice that it opens the throttle fully with less effort since it is under driven. no real performance gain, but they do fake the funk with throttle response.

yes but the real question is if the s14 and s13 sr20 or ca18 throttle pulleys are interchaneable?

are you running the ka or sr motor?

They are interchangable somewhat. But you cant use a s14 pulley/s13 throttle body on a s13 sr20det. The cable wont be the right length. And also vice versa. You cant use a s13 pulley/s14 throttle body on a s14 sr.

The butterfly shaft sizes are different so sometimes they will or wont swap over. You should be able to see difference in this picture. And why are you asking this? Do you need a pulley. I have a s13 throttle body I can sell you. Its the one in the picture.

but I'm going to be running an isis intake manifold on my car (similar the greddy) it has Much shorter runners and moves the throttle body to the top of the engine bay

at this point, will my throttle cable have enough slack to run the s14 pulley? I already have a stock pulley, but I'm looking at the underdrive ones on e-bay and they don't list one for the s13 sr20det. only the s13 ca18, and the s14 sr
